vmcmnxassarmiaor BERLIN, GERMANY, ASSIGNOR r THE FIRM. MULLER aantinsrmu,-ELeEnsBUneEn rnunaznoeranmx, or ELeEnsBUne, GERMANY 21301110310 LIGHTER Application med September as, 1927, Serial lighter ofthat kind wherein by rubbing on the surface of a p'yrophoric body 'suchas an alloy of iron and cerium sparks are produced which light vapors ofa liquid fuel such as gasoline, emanating from the end of a wick whichpasses through the wall of a fuel receptacle.

My invention has for its purpose to produee a lighter which can beeasily. and .efl iciently manipulated with one hand only and which canvery cheaply .bemanufactured. In order to secure these results I providethe lighter with a pivoted member mounted on the fuel receptacle, saidmember forming'a closing cap for the opening of the wick tube andcarrying a friction body adapted to rub on the surface of the pyrophoricbody of the lighter and in order to actuate this member I bring it inhinged connection with an actuating lever which is pivoted at the endopposite to that connected to the cap member to a bearing block mountedon the fuel receptacle. In order to secure reliable operation, I providea sliding connection between the actu-- ating lever and its pivot andspring means for positive closure of the wick tube cap.

In the accompanying drawings, Figs. 1, 2

and 3 are side elevations, with parts shown in section, of threedifferent embodiments of the invention.

' Fig. 4 is-a fragmentary side elevation-of the device shown in Fig. 1,the parts being shown in the relative positions which they occupy priorto mounting in or on'the ireceptacle, and 1 F 'g. 5 is a fragmentaryside elevation of the device of Fig. 2, the closing cap being shown inopen position. Y 1

The-preferred embodiment is that of Fig ures 1 and 4. wherein 1designates the'fuel receptacle, 2the wiek tube and 3 the usual fillingscrew. 4 andv 5 are bearing blocks mounted on the fuel receptacle, thelatter fixedly and theformer removably. Bearing block 4 is provided witha tubular extension 6 removab y inserted intoa tube 7 which is firmlyand tightly connectedwith the bottom and cover of the receptacle 1.Within the 5 tubular extension 6 there is inser eda spring No. 222,604,and in Germany August 2, 1927.

' 8 seated on a set screw phoric body 10.

Pivotally mounted on bearing .bloek 4is a member 11 having its pivot at12 and formlng a closing cap 13 for the free. upperend of wick tube 2.14 is an actuating lever for the pivoted member 11, said lever being 9and carrying a pyrojointed'by a connecting pin 15 to said member 11 andpivotal about pin 16 carried by block 5. The end of said actuating lever14 is provided with a slot 17 wherein pin 16 is adapted to slide; ablade spring; 18 being pro- .videdtending to press the lever 14 towardsmember 11. 19 is a friction wheel firmly (iii substantially firmlymounted on member The operation is as follows: On pressing the actuatinglever 14, member 11 is turned about pivot 12 opening cap 13 and rotatingwith it friction wheel 19 so that the wheel rubs on pyrophoric body 10and produces sparks for lighting the wickin wick tube 2 at its upper endwhich now is free from cap 13. On restoring lever 144:0 the positionillustrated in Figure 1 of the drawing, cap 13 is automatically pressedon the cover of receptacle 1 by the action of spring 18 owing to pivot15 being positioned above the straight line connecting pivots 12 and 16.

- It will be noted that the axis of the pivotal connecting pin 15.movesthrough the plane defined by the axes of pivot pins 12 and 16 when thetoggle linkage is operated to lift the extinguishing or closing cap. Thepres sure of spring 18 therefore yieldingly retailfs the toggle linkageat both limits of its range of movement. The toggle is broken to liftthe cap 13 and oscillate the abrader by pressing the thumb down upon thelever 14, and the ca is restored to position over the wick by sliing'the thumb-along the member 11'to rotate the same about the axis ofthe abrader. I I

In order to replace pyrophoric body 10, the bearing block 4 togetherwith member 11 and lever 14 may be removed, whereupon set screw 9 andspring 8 can be-removed from tubular extension 6, so that a fresh,tageous since the device may be operated by is slidinglygui ed, saidguide being mounted, by pivot pins 16*, for rocking movement upon thebearing block 5*. 18 is a coiled spring mounted on actuating lever 14:tendmg to cover 0 phoric body which in this case is in the form of adisc and yieldingly supported on a spring member 21; 19 is afriction pinadapted to rub on the pyrophoric body ,on rotating of cap member 11*about pivot 12.

press cap member 11" down on' the .The operation of the device issubstan tially the same as that of-Figures 1 and 4, so that nodescription thereof is needed; parts having-l the same function as partsappearlng in t 4, being desi nated with the .same numerals with theaddltion of the letter a 4 The embodiment illustrated in'Fi re 3 is verysimilar to that of Figures 1 an 4 ex.- cept that the yielding connectionbetween lever 14 and its pivot 16 is replacedb a yielding connectionbetween bearing bloc 4" provided. Thereby the necessary displacement ofthe parts of the device on actuating lever 14 is made possible.

I claim: 1. In a pyrophoric lighter, the combination with a fuelreceptacle and wick, a member carrying an abrader and a closing cap, andmeans on said receptacle providing a ivotal support for said member, ofa secon member disposed on the top side of said receptacle a directpivotal connection between said mem ers, and means on saidreceptacleproviding a tpivotal support for said second member, e axes of the threepivotal con nections being disposed above the top ofsaid fuel receptacleand so related that the said members form a toggle linkage operable,

upon application of pressure transversely of said second member, torotate said first member.

2,.A pyrophoric lighter as set forth in claim 1, wherein one of saidpivotal sup ortabout itspivotal supporting means to actuing meanspermits the member carried t ereby to move axlally wihh respect to saidre-' ceptacle when sald second member is tilted ate said .firstmember;
